Abstract

Alkanes are catalytically oxidized in the absence of ammonia by passing a feed gas including the alkane and oxygen at an elevated temperature over a solid catalyst. The partial pressure of the alkane in the feed gas exceeds 0.70 atmospheres absolute. Examples of the catalytic oxidation are the production of acrolein and methacrolein and acrylic acid and methacrylic acid from propane and iso-butane.
